IMPROVEMENT m DlTCHlNG-MACHINES.

Specification forming part of Letters Patent No. 159,371, dated February 2, 1875; application filed December 26, 1874.

To all whom it may concern:

Be it known that we, JACOB F. WILLIAM- sort and J AMES H. 80mm, of Harler township, in .the county of Clay and State of Illinois, have invented a new and valuable Improvement in Road Ditcher and Grader; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing is a representation of a plan View of our machine, and Figs. 2 and 3 are side views of the same. Fig. 4. is a modification of our machine, and Fig. 5 is a sectional view of the same.

This invention has relation to machines for making ditches and grading roads; and the nature of our invention consists in combining with an inclined elevator an endless carrier and a plow, which are both hung in such manner that they will accommodate themselves to inequalities of surface passed over, and can be adjusted higher or lower as circumstances may require, which adjustment can be effected by the driver, whether the machine be in motion or at rest. The invention also consists in a novel mode of arranging and hanging the plow which throws the earth upon the elevator, so that such plow can be raised or depressed by the driver sitting in his seat.

In the annexed drawings, A designates a rectangular draft-frame, which is mounted on two transporting-wheels, B B, one of which is a driving-wheel. The shafts a a of these two wheels can turn independently of each other and on the face of the wheel B a beveled spur-wheel, b, is secured, which engages with a beveled pinion, c, on a longitudinal shaft, 0, having its bearings in the frame A, and also in an auxiliary frame, A. The pinion 0 is adjustable on its shaft 0 by means of a lever, 0 and a draw-rod, 0 which latter extends forward to a position convenient for the driver, sitting in his seat S, to work it. This adjustment of pinion 0 allows the driver to stop or start the shaft 0 at pleasure. The drivers seat S is located at the middle of the length of the front beam of frame A, and the draft-pole is arranged directly beneath this seat. D designates an inclined frame, composed of two parallel side boards, which are connected together in a suitable manner, and" 9, which will be provided with buckets f, if

the machine is used on timber-roads and in ditching. For prairie-land the buckets may be omitted. The earth is thrown upon the elevating-belt g by means of a plow, G, the beam G of which is applied between vertical guides h, depending from the righthand side of the frame A. The front end of the plowbeam is suspended from the frame A by means of a link, i, and the rear end of this beam is suspended from the short arm of a lever, H, by means of a link, 2'. The front end of lever H is within reach of the driver when in his seat, and this end of the lever is held by means of rack-teeth and a spring, shown in Fig. 2. It is by means of lever H that the driver can raise the plow out of the ground. The frame E consists of two sections, which are joined together at j, so that a limited articulation is allowed the shortest section. The endless carrier F, which is carried by the frame E, passes around two drums, 7c is, and is sus tained at intermediate points between these drums by means of rollers 10 10 The drum is has a sprocket-wheel, Z, on one end of its shaft, over which a chain, on, passes, which chain also passes around a sprocket-wheel, l, on the rear end of the shaft 0. The carrier F is thus moved in the direction indicated by the arrow in Fig. 1, when the machine is drawn along. Another sprocket-wheel, P, on shaft 0, communicates motion to the roller 01 of the belt g, by means of a chain, a, and a pinion sprocketwheel, a, which latter is on the shaft of said roller d. The frame E articulates vertically about the shaft 0, and is hung by links 0 o from the frame A, so that it will not bear with its full weight on said shaft. Near the point where the elevating-belt F delivers the earth upon the carrier F, a bail, p, is attached to the sides of the frame E, and connectedby a link, 1), to the short arm of a lever, L, which lever has its fulcrum on a post, L, rising perpendicularly from the frame A. The front end of lever L is near the drivers seat, and is held in place, after adjustment, by means of a rack and spring. The lever L enables the driver to raise or lower that end of the frame E which carries the endless elevator g without in any manner interfering with the rotation of the elevating and carrying belts.

In practice I shall employ a caster-wheel support, P, for the lower end of the elevatorframe D also a supporting-wheel, P, beneath the frame A.

What we claim as new, and desire to secure by Letters Patent, is- I 1. In a road ditching and grading machine, the combination of a plow, which is suspended as described, with the elevator g and carrier F, substantially as specified.

2. In combination with a plow which is suspended by means of linksi i, the lever H, and the elevator g, and carrier F, substantially as described.

3. The carrier F and elevator g, movable about the driving-shaft G, in combination with a plow, a draft-frame, and the driving and transporting wheel 13, substantially as described.

In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.
